3CX vs Microsoft Teams

3CX is a business communications platform that replaces traditional PBX hardware with a software-based phone system. It supports voice calls, video conferencing, a website live chat widget, and call center features like queues and reporting, and can be deployed on-premises, in a private cloud, or via 3CX's own hosting service.

Microsoft Teams is a unified communication and collaboration platform bundled with Microsoft 365, combining chat, video meetings, and file sharing built directly on top of SharePoint and OneDrive. It is the default hub for meetings and internal messaging at organizations already standardized on Microsoft 365. Teams organizes work into teams and channels similar to other chat platforms, but is distinguished by tight integration with Word, Excel, PowerPoint, and Planner, allowing documents to be co-authored directly inside a channel without leaving the app. Meetings support up to thousands of attendees with features like live captions, together mode, and background noise suppression, making Teams a common choice for both daily standups and large all-hands meetings.
